O doplňku
Mass Emailer Send professional email campaigns directly from Thunderbird, with full control to avoid server blocks.
Key Features:
How It Works:
Known Issues:
Key Features:
- Control outgoing rates to avoid being flagged as spam
- Send bulk emails using your Thunderbird accounts
- Manage up to 6 active campaigns
- Import recipient lists and use dynamic placeholders (e.g.
{{name}}{{email}}{{company}}) - Send emails with rotating subject lines
How It Works:
- Install the add-on and create your first campaign to open the Campaign Manager
- Select a folder containing your template email
- Assign a template to your campaign. If you are using placeholders, make sure they match your uploaded recipients table. E.g. placeholder
{{name}}should match the column "name". To:{{email}}should match a column "email" - Choose whether to send now or later (sending later places emails in your Outbox)
- Set your sending rate (e.g., emails per hour)
- Enable Random Mode to introduce time variation (e.g., if sending 1 email every 10 seconds, actual interval will vary between 6–18 seconds)
- Enable Logic Mode to create batches with cooldowns (e.g., 25 emails per batch with a 5-minute pause)
- Use Template Sender to send from the email shown in the template
- Or select a different email account to override the sender in the template
- Import recipients from CSV or Excel (first row will be column headers used as placeholders in your email body)
- Click Run Campaign to start sending
Note: Using Microsoft Email Essentials, we successfully delivered 500 emails in one run with a rate of 260/hour, using Random + Logic Mode (25-email batches with 5-minute cooldowns).
Known Issues:
- Restarting the email client will delete all campaigns
- After long periods with the add-on closed, you might need to deactivate and activate the key again
- Sending emails is intentionally slow to deal with erratic OnStopCopy Error (0x80070057) and allow recovery
